AAF filters are designed to protect all industrial equipment located downstream in the compressed air system. They provide effective removal of solid particles, water, oil aerosols, hydrocarbons, odours and vapours from compressed air systems up to 16 bar. The compressed air quality required by ISO 8571-1 can be achieved with 5 different grades of filter elements (P, R, M, S and A). Internal and external condensate traps (optional) must be used for effective drainage of condensate from the air filtration.
